A couple of ideas

First of all. Thank you. 

By using zwift after knee surgery in november to aid in recovery after being ran over by a car I have lost over 25lb.

Idea number one. How about a bit of discount if we were to commit to signing up for 12 months at a time. Say a 10% discount if we pay for a full year up front.

Idea number 2. Please re-create some real life grand tour climbs. i would love to train for alp du huez or mont vonteux from the comfort of my home.

Other than that keep up the good work.

Both have been suggested a few times, make sure you vote up the existing requests so Zwift knows what the users want.

BTW, you can subscribe for a year and get Bicycling Magazine free.
